So, I tried an all perlite grow not too long ago, and let's just say, it didn't go well. I ended up pulling her about a week ago, and I'm trying not to look back, but trying to move forward with some success. I didn't do the reaserch and my plant payed for it. So this time, I'm hoping things go a bit smoother. This time, I've started them in rock wool, properly preped, instead of soil. So far, four of the seven have sprouted. I've purchased some perlite frome the local hydro store. Some real "chunky" stuff. A lot bigger than my last stuff. I also bought a block of this coco stuff I've heard so much about. The dude at the store suggested I try this instead of perlite, or a mix. I'M TRYING ALL THREE! One perlite, one coco, and on 50/50 mix. Any helpfull tips? What's the proper way to prepare this coco?
